Toplevel parser: reads in a given single Hugs Core file,
starts the module parser with empty state. The function
returns either a parse error or an individual Yhc Core in memory.
Due to the Hugs specifics, individual Yhc Core modules are not
usable, so it is recommended to use the linkHugsCore function
unless anything special is needed.

Hugs Core Linker: reads in all *.cor files from the given directories
and produces a linked .yca object ready to save in a file.
Names of reachability roots are picked from the arguments,
and they should be fully qualified names with
semicolons separating module name from function name.
If an empty list is provided, all "main" functions
found in all modules will be used as roots. If none exists,
error will be reported. Error will also be reported if parsing
of any of the files, or final linking results in an error.
